First we need to understand how Wi-Fi technology works. When you connect a device to your network, give it a local IP (Internet Protocol) address is assigned. This is a unique label that identifies each device on the network. Well Turkish Identity Number You can think like. These internal IP addresses are usually 192.168.0.xxx format. Here xxxis an identifying number between 1 and 255.

Most modems automatically connect to devices when a connection is established. assigning IP addresses for DCHP(Dynamic Host Configuration Protocol). However, as the name suggests, these dynamic They are IP addresses, so over time as the device shuts down and reconnects to the network they can change. If you do not want a device’s IP address to change in this way, you must specifically assign it a permanent static IP address.

Dynamic IP addresses because it changes frequently, it is not a useful way to identify a device. Instead, the device Media Access Control (MAC) You can use the address. This is the manufacturer-assigned unique is an identifier. These internal IP addresses identify devices connected to your Wi-Fi router. However, connected to the Internet your modem is himself.

As a result, your network devices share the same external IP address, but unique they have internal IP addresses, which is the main reason your modem can make a distinction. Given these addressing mechanisms, you need to use it to identify devices on your network and detect suspected devices. There are certain methods.

Controlling devices on the network from the modem interface

Most home modems have a dedicated web interface where you can access information about the external internet connection and connected devices. There are different IPs depending on your modem to access this interface. 192.168.1.1, 192.168.2.1, 192.168.0.1 One of their IPs (most likely 192.168.1.1) will work.

The device name is usually the manufacturer determines so you can easily identify your smartphone and laptop. However, peripherals, smart home equipment, and older devices may not have a structured name or just show a set of characters. If you notice a device you don’t recognize, You can disconnect each of your networked devices one by one.

Keeping your network safe

In this article on Wi-Fi security, we have given you information on how to check the devices connected to the network and what to do about suspicious devices.
